So, the problem is narrowed to the wireless LAN interface not communicating with the local network. Searching on the error message you posted finds several hits. You could also edit your question again to focus on the S1 Wireless LAN error.

Please report what happened when you tried wired Ethernet. Also, return to the WiFi configuration and re-type the SSID and password; report the results.

Yes, you'll still need an Internet connection to do updates, but fixing the local network connection is quite likely also to fix Internet connectivity.

Note for others: ping google.com works very reliably if network connectivity and DNS are good. The address 8.8.8.8 is one of Google's public DNS servers. If pinging by address works and by name does not, the problem is quite likely DNS resolution.

Try an Ethernet connection. Try rebooting after you've connected the Ethernet cable. If still no-go, try a search on "raspberry pi troubleshoot network." If necessary, open a new question here for troubleshooting help, or completely revise this one to be a network problem.

Your Pi does not have network connectivity. Are you using wired or wireless connection? And, I'm guessing that you do have monitor and keyboard connected, right?
Bob Brown
Jun 10 06:55
OK. Either no network connection or DNS failure. Try ping 8.8.8.8 If that works, it's DNS. If not, find the address of a device on your local network and try to ping that.
Bob Brown

Not an answer because I'm unsure, but "Temporary failure resolving..." looks like DNS isn't working or you have no network connectivity at all. What happens when you ping google.com ?

@JarrodChristman "I have my own reasons for being late." And professors have their own reasons for not wanting classes disrupted by latecomers. Regardless of measures taken to reduce or prevent lateness, being late, especially repeatedly, is just plain rude.

I once attended an institution where no one was ever late because the door was locked when class began. (Not a safety hazard because easily opened from inside.) There was also a rule that three absences caused one to be dropped from the class with a grade of F. Really, no one was ever late, at least not twice.

Years ago the president of the university where I taught regularly brought her Doberman to campus. I met the dog for the first time on the quad after having served pizza at an event for gradual students. I got the lick-and-wag treatment. For ever after the pres was convinced that I am a Good Guy.™

@DikranMarsupial Quoting Ed Yourdon, "Yes, but my program works and yours doesn't." a) It is trivially easy to test whether programs compile without fatal errors, and b) A program that will not compile can never work. Problems, if any, of compiler and flags compatibility should be addressed as part of the course design.
Bob Brown
May 9, 2022 13:38
I suggest that it is never OK to turn in a programming assignment that won't compile. That shows a lack of effort, no matter how much time was expended. OP complains that the professor would assign a zero for an assignment with compiler errors. So would I, even for first year undergraduates.

@Buffy I'm with you about competitive grading, but in this case, and without competitive grading, an extra ten minutes could be the difference between A and B. It would be interesting to know how many people in each section did not complete the entire exam.

@JonCuster Right. I used to put my notes, slides, and assignments on the public web. Then we got a course management system. I had to put stuff there, and putting it also on the public web and keeping that organized became an extra chore.

Sadly, a quote from the piece in The Atlantic to which you have linked contains the necessary warning: "...the fact that smart, busy people felt it necessary to investigate Sheck for mouthing the word when referring to it—not using it independently, much less directing it at someone—suggests a preoccupation less with matters of morality than with matters of taboo."

I began recording my lectures when I had a class of 60+ students for most of whom English was a second language and Southern a very distant third. Recordings will never harm students who want to learn and may help some of them. I retired three years ago. Earlier this fall I got a request for my recorded lectures from a student who is struggling with a class I formerly taught.

The answer doesn't say "demand." It says "ask." Try this: "Professor, while I understand there are dire consequences for cheating, given the circumstances it seems likely that some will. If so, relative marking seriously disadvantages honest students. Could you please reconsider your marking decision?"

@AnonymousPhysicist True, but it is relevant to on-line conferences in general. For example, I'm using Blackboard Collaborate, not Zoom. Perhaps its lower profile makes "Collaborate bombing" less likely. I remain concerned because I have middle-school kids in some of my sessions.
Bob Brown
Apr 7, 2020 18:39
@AnonymousPhysicist It probably is "boat programming," but it's of keen interest to academics right now. What is on-topic is that there are some ways to vet academics, such as .edu email addresses and faculty web pages on a university's site, that aren't applicable when the audience is the general public.
Bob Brown

Zoom has made changes to the settings of free and paid personal calls that reduce the probability of Zoom Bombing. Requiring passwords and the "waiting room" feature might be enough for meetings where the organizer knows the expected participants.

@JoErNanO I don't know about the U.K. or China, but in the United States, a Ph.D. dissertation is absolutely not in the public domain. Many people, including me, choose to make our work open access, but that's a choice, not a requirement.

@Spark Oh. That does put a different light on it. It sounds like having the student removed from class is the only workable option.

Sounds like your harsher comments have the intended effect. Don't feel guilty. As you have pointed out, other students are suffering because of this behavior.

@DanielR.Collins: I have come to believe that a bimodal distribution is expected and good. The first time I aw one, I asked a professor with much more experience than I. Tapping the high end of the chart he said, "It means that these students get it and," tapping the low end, "...these students don't." The ones who work and study get it, and the ones who don't, don't.

@user2768 Microsoft's delivery model as of Windows 10 is "Windows as a service." All those "End of Service" dates mean is that you must keep at least reasonably current on Windows updates if you want a supported version of Windows 10. Further, Windows won't grind to a halt if you do defer updates and pass the End of Service date.

@VoodooCode Do note that the answer in Information Security conflates disclosure of data Microsoft already has, e.g. email, in response to legal process with collection, use, and disclosure of diagnostic data.

When I assigned group projects, a majority of students in a group could "fire" a group member. In that case, the fired group member had to complete the project solo. No one ever got fired, and I got no complaints of non-participation.

@guifa It's not a question of technical expertise; it's a matter of money. I have captioned video and also edited automatic captions to improve usability. Minutes of captions take hours of manual labor. There is a limit to how much labor an institution can put into content which benefits the public but does not generate revenue.

Bob Brown
Jan 17, 2017 02:25
I require my students to submit work in Word because I do not then have to use two or more programs myself to open student work. The university provides MS Office to the students, and I require them to use it. Unless you would have to pay the full retail price for MS Office, just get with the program and do what they've asked. I promise it won't kill you. (It won't kill you to use an OS other than Linux, either, even though Linux is also my preferred platform.)

@LostWanderer: I am in agreement with the accepted answer. The purpose of education is to learn. The purpose of assessment is to measure the degree of learning. Anything that undermines the integrity of the assessment is academic misconduct. For a more thorough discussion of the purpose of grades, see this: academia.stackexchange.com/a/31448/16183

@LostWanderer: Check your student handbook, code of conduct, or whatever. Where I teach (in the U.S.) the student code of conduct prohibits "Receiving, attempting to receive, knowingly giving or attempting to give unauthorized assistance in the preparation of any work required to be submitted for credit." Further, "unauthorized" is anything that is not specifically permitted.
